“The distinguishing feature of the Comprehensive Meta-Analysis Software Programme from the other Meta-Analysis Software Programmes is to be most practical and to be understandable easily. While using the programme the only thing should be done is to enter the necessary data into the data sheet and to click on the relevant buttons. That's all. No need to calculate the statistical formulas by hand to reach the effect sizes, anymore. I would like to send my special thanks to you and your team from Ankara University, Ankara-Turkey, Sevgi Guney, MSc in ClinPsych, MAPS.”

“Comprehensive Meta-Analysis is a state-of-the art, versatile, and user-friendly program that has met all my research needs for conducting meta-analyses. The supporting documentation is first rate and the support staff are extremely helpful. I highly recommend this program for anyone engaged in meta-analytic investigations.”
